Product Description

Compressors are often placed outdoors and are exposed to adverse environmental conditions such as humidity, pressure, vibration and various chemical influences. At the same time, compressors utilizing CO2 as a refrigerant operate at pressures and temperatures (up to 180ºC) much higher than conventional compressors.

Product Advantages

With harsh environmental conditions acting both within and outside of the compressor, it is necessary that the housing is durably and hermetically sealed to ensure the continued safe and reliable performance of the compressor. This is why glass-to-metal sealing (GTMS) technology is the most promising solution for CO2 compressor seals, since GTMS consist only of very resistive materials.
